For the best experience on our site, be sure to turn on Javascript in your browser. The INFINITube family is the ideal system for creating collapsible and open booms. The frictional forces coupled with distortion of resilient plastic parts of the device inhibit un-turning or counter-rotation of the parts. The brackets may be screwed or nailed to the opposing sides of the frame of the opening. Telescoping models can be adjusted to any desired length and securley locked in position with an effortless twist of the inner tube. On the other hand, a user can overpower those frictional forces by reversing the twisting motion associated with tightening, and thus can loosen the locking assembly and remove the curtain rod from its locked-in position. The shaft may be a plain smooth shaft, a shaft which has a diminishing thread running from the small end of the screw, or a shaft which has threads that are small so that they insufficient to well-engage the threads of the sleeve. The shape of the taper may vary within the invention. In another embodiment, there is no shaft portion, the screw is tapered and the threads may change in pitch or profile at the larger end of the screw.
